IMPROVEMENT IN RANGERS POR SHAFTING.

'.lO ALL WHOM IT lMAY CONCERN:

Be it known 'that we, GEORGE AW. HUBBARD and SCOTT A. SMITH, both of the city and county of Philadelphia, in the State of Pennsylvania, have invented new and useful Improvements in Hangers for Shafting; vand we do hereby declare that the lfollowing is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this speciu'cation, in which- Figure 1 is an elevation of the hanger A.

Figure 2is a vertical section through a: 9:.

Figure 3 is a horizontal section throughtheline y y.

The general construction of this hanger is what is 'known as the ball-and-socket pattern, that is, the boxes c and d are held in podsition by two concave-ended adjusting-screws a' a', in contact with corresponding convex surfaces on the top side of the upper box c, and the bottom side of the lower box d. These screws a a have' square penings a a in their centre, into which may be introduced the square end of a'wrench, for the purpose of screwing them up or down, in adjusting the boxes c d, and firmly holding the same.

The set-screws b b keep the adjusting-screws a a from being displaced, after having been properly adjusted.

The above-described peculiarities of thishager are old and well known, and to them we lay no'claim.

The first part of our invention consists in so constructing this hanger A. that one patternv may be used for several sizes of shaft, while at the same time the material is put into such form that it-acts to the be'st advan tage in securing strength and stiness. This result is accomplished by making the body of the hanger hollow, (as shown oy the dotted lines at b in fig. 1, and at 6 in figa-3,) and by using coresof dicrent sizes in the space b, in combination with a space at Blarge enough to receive between the ends of the adjusting-screws a a,.the. several sizes of boxes., i

In practice, we find that three sizes of shafts for each hanger-pattern is the number which can be used to the best advantage, as, for instance, a twoinch, two-andaquarterinch, and two-anda-halfinch bore of box.

The new results obtained by this improvement may be stated as follow: irst, a simple pattern may be used for several sizesI of shafts second, a very stilhanger is made with a minimum of metal; third, a very strong hanger canA bemade for special uses, as,for instance, 'the hangers in a main line of shafting, which takethe strain from an engi-ne, by` much reducing the size of th core-b". i

The second 'part of this invention consists in a method ofadapting a self-oiling apparatus to hall-andsocketl hangers, whether made with or without the above-mentioned improvement,

In combining a self-oiling apparatus with a ball-and-socket hanger, our object is to vprovide means for bringing the reservoir of oil close to the lower side of the shaft, and at theI same time in the centre ofthe bear,- ing, as we believe this tobe the point at which oil shouldj be applied, particularly in aball-and-sockethanger, in which the centre ofthe bottom box is the point at whichlit would rstheat, in the absence of oil, because it there restsuponthe adjusting-screw a. It is also quite requisite vto"the successful working of a self-oiling apparatus, that some means should be provided for readily removing the same for examination. These requirements aremet, and this part ofour invention consists solely in utilizing the space in the centre of the bottom adjustingfscrewva, for conducting oil,by capillary attraction, or other equivalent means, tothe bottom. of the shaft, in combination with an opening in the bottom box, and a. means for returning the oil to. a reservoilyto be again raised to the shaft. One mode of utilizing the space' in the c entre ofthe adjusting-screw a', is hyenl'arging the opening a", and forming a reservoir at e, in combination with the circular opening 0, iu'the centre of the bottom box. Into this reservoir c is-introduced a piece of wood, L, covered with the lwick l, all enclosed in the oylinderof tin/l. The tin cylindeiV-wic-k, and wood are fastened together by nails at n.' A spiral spring, N, 'forces the wick up against the shaft. The oil isdrawn up through the wick 'by capillary attraction,`

and flows out on the shaft as far asthe recesses c c', in the ends of the boxes', and isr'eturned again to the reservoir by means of a channel, d', cut in the bottom of the box d. Openings are provided at d, into which oil 'may be poured atan;r time, to ll up the reserv'or c.

'made for the pnrpose specified.

To remove the reservoir c for examination, it is only necessary to prop up the shaft and unscrew the reservoir a', rst marking it to its place. y

\ What we claim as our invention, and desire to secure b'y Letters Patent, is t 1. The, cored spaces b', in combination with the enlarged. opening B, in a ball-and-socket hanger, when 2. lThe cvombinationof the oil-reservoir c, in the lower adjusting-.screw a', with `the opening o and the channel d in a ball-and-socket hanger, all constructed substantially as described, and for the purpose specified.
